I have had Keeleazy on the hull of my 14' Pro Angler for about 3 years now. The downsides are the cost and it does not fit the contour of sharp angles well. It has been cut in one spot on the front of the hull from concrete launch ramps but has otherwise held up well and the glue has stuck all that time. The shop where I got the Keeleazy only had enough black tape on hand to cover what you see in the pictures. I need to get more tape and cover more of the hull that have scratches. This PA is a 09 and has been used for 5 years. The trailer is a post WWll (1947 vintage) 1/4 ton Bantam trailer.
